I can’t think of any site with more inspiration or resources than deviantArt. It is a must for everyone interested in design. The one feature I like the most is the favourite-service. Not only can you add artworks to your favourites, but you can sort them into different collections. I’ve compiled a list of the 14 greatest collections on deviantArt. The themes vary from typography, advertising to photography. There should be something for everyone. Assuming that each collection contains about 40 designs you’ll get 500+ (no guarantee) inspirational artworks. Enjoy!
